I like building models. Gunpla or wargame minis currently, but I’ve also recently taken up 3d printing as a hobby. Not the cheapest hobbies unfortunately, but ones I enjoy.

Making things, learning things.

E.g.:

• painting

• clay/ceramics

• learn a language

• learn the history of a region

• visit a museum

• grow vegetables

• make pickles

• learn a weapon

I got into designing crosswords for a while. It was pretty fun to manually lay out a sheet of answers and think up clues for them. Also, reading theory.

I started with crochet about two months ago (my 53'rd attempt at a new hobby) with the idea of wanting to make Amigurumi. But it kind of (d)evolved into just experimenting blindly with different stitch combinations and turning them into bracelets for myself. But I'm still having fun with it :)
It's relaxing, relatively cheap (for what I do with it) and I feel motivated to slowly try to improve myself. I still feel anxious trying to complete any major project though, but that's just me. There's a sad unfinished amigurumi monster in my drawer, waiting for me to work up the nerve to stitch him together :)

Anything you enjoy that you could improve on!

Currently I'm spending more time learning guitar.

I think as long as you're genuinely interested, learning things becomes a lot easier.

Brazilian Jiu-jitsu. Will keep you fit, you won't be able to think about your life problems for 1-hour ... guaranteed, you'll make new friends, you will build mental resilience and you'll learn self-defence. So many benefits as long as you train for the long-term and avoid injury.

Fun ways to spend your time:

Walking, running, hiking, cycling, transitting to a nice spot in town you've never been. Fairly cheap, and fun way to get out and forget the rest of your problems for a bit.

Sports and Yoga, cooking and baking, sewing, learning an instrument like guitar, piano/keyboard.

For things that aren't mindless fun but useful long term: Try learning a new language! It's kind of difficult but it's cool when you start to figure out tiny tidbits of other languages.

going outside, musing around, gazing at the clouds and plants and all

Sewing is a nice thing to learn because you can always touch up your own clothes and if you like you can buy a cheap sewing machine and do your own shirts, pants etc

I went back to school. You can find tons of online courses in just about any subject, and some will count for real college credit if you ever want to turn it into a degree. Many are free, but some will cost you and most are worth it. A way to make your addiction productive.

I always recommend roleplaying games like DnD or pathfinder as a hobby since it has a built in social and private element to it. You can join a group at most local game stores or by looking for organized play. Both Pathfinder and DnD have organized learning sessions where you can learn to play. Both allow you to start for free.

The good part is there is a regular scheduled social element usually weekly and between time you can do things yourself. That includes reading rules, making minis, practicing voices, writing modules, reading old source book, watching live streams, making maps etc. You don't have to do all of those but you can really go in depth or as shallow as you want. All of the things you do my yourself will enhance the enjoyment of the group which is a great as well.

I do a lot of creative writing. Remember that what you write doesn't have to be "good" in order to be worth the time you spent doing it.

You didn't rule it out, so my first thought is: play video games! It's certainly on the line between consuming something and learning to do something. Some individual games can be a whole skill to study and hone for years (eg, learning a fighting game or a speedrun, etc etc)

Spirit of the question though, that would probably be considered content.

Other ideas, most already covered by other comments: art, photography, music, writing, programming, cooking, woodworking, or learning a new language.

The 'fun' adjective means everyone's answers will be different! For me, exercising is good even if many times it ends up being a VR adventure or workout.

I enjoy growing a small garden! You might not xD

Pick up some acting classes and volunteer down at the local theatre to learn more about yourself, your expression to others, learn the intricacies of a great classic story and make new friends!

Really, just pick something and go to the moon with it

Instead of playing video games, I'm leaning frontend programming. I'm making a chatGPT movie recommendation assistant right now. Finishing projects supplants the dopamine hits I got from gaming.

Thrift shopping is great. Window shop at antique stores, goodwill, pawn shops, thrift shops. Even without buying things you can come across lots of interesting finds.

Find your local free community center. Your local library is a good start. There's bound to be countless free activities or events to join and also meet people at to make casual friends while doing new things.

music is life <3

I got into scratch/trash building and kit bash modeling crazy mechs and stuff last year and it’s been a blast.

List of things you would do with friends like going to a bar, to a movie, eating wings/dinner, driving somewhere fun, or going on a trip then do the list alone.

Is reading technically considered consuming content? Fun and it’s a pretty cheap hobby if you have library access or go to used bookstores!

Multiple times I have found satisfaction and joy in reading non-fiction or how to books about a certain topic and then deep diving. With a library nearby you can avoid spending any real money. Almost every book about a topic has other books as references or recommendations which leads you down a hole of information about things you can learn about and implement. I am currently deep into a research hole about plant identification, herbalism, wild food forging and permaculture. This is great since I can then implement these in my garden this spring but I enjoy the learning part just as much as the doing. Its a fun way to see what interests to you. It doesn't have to last forever but you will keep the knowledge

Meta answer.

To me personally any sort of addiction is a symptom of feeling out of touch with life. It's a kind of rejection of what is and slapping a bandaid on that pain by constantly asking for more. More food. More content. More whatever.

It's a desire that can't truly ever be satisfied.

It's important to take a step back when you feel lost in such a stream of more. Instead of trying to change things, try to accept things as they are. You can always decide to change it later. For example when you wake up, just take a few moments to experience waking up, rather than immediately focusing on what needs to be done.

When it comes to doing anything, play around with how much care you put into it. Try doing it quick and badly and without any care. And try doing it with utmost care and perfection. Think of it like training your ability to control the number of fucks you give for any specific thing. That way you can let go of control by giving up your need for change, but also regain it for the things that really matter.

And then it's a matter of trying out many things to see what resonates with your personality. When you find something you can sharpen it by removing the things that don't really matter to you.

For example you might figure out that you enjoy painting. You'll probably come up with lots of unnecessary goals for yourself such as being able to paint realistic portraits with oil. Whereas actually you would have enjoyed art history more, or perhaps drawing childish looking animals with crayons.

If you had held onto the idea that you need to do oil portraits, you would've just saddled yourself with another thing that you only partially enjoy, and so you might just leave it laying around. It's just a disconnect from who you really are. You'd be imprisoning yourself again with a need for more, instead of realizing that you are free by nature and that it's alright to enjoy seemingly unimportant things.

Playing any musical instrument. The feeling of your practice grindings pay off, no matter how still mundane it is to compared to social media professional musicians, is a pretty good feeling.
